Yep, it appears that after a 3-13 season, Karl Dunbar might wind up as the only coach fired from Leslie Frazier's staff.

According to an NFL source, the Vikings are now in position to finalize their coaching staff in time to lead the North squad at this year's Senior Bowl. (That's a week-long event that begins Sunday in Mobile, Ala.)

But for those who wanted or expected a major overhaul, it's not coming.

Here's the full Star Tribune story on how Frazier's staff has now been tweaked and changed. In a nutshell, here's what you need to know:

The Vikings have great optimism that Alan Williams will soon agree to become the team's new defensive coordinator after spending the past 10 seasons as the defensive backs coach in Indianapolis.

Fred Pagac has been removed from the defensive coordinator role but will remain with the team, returning to a position as linebackers coach, which he held from 2006-10.

Current linebackers coach Mike Singletary will share some responsibilities with Pagac as it relates to working with the linebackers and will also retain his title as special assistant to the head coach.

And to fill the vacancy created when Dunbar was fired, Frazier will bring Brendan Daly back to the organization as the new defensive line coach. Daly spent the last three seasons with the Rams but was with the Vikings from 2006-08 as an assistant defensive line coach.

As for what else the Vikings might be able to do to shake things up and improve upon this past year's 13-loss headache? Well, don't be surprised if newly appointed general manager Rick Spielman begins to leave his mark on the roster with a concerted effort to get younger.
